A guide to the Book of Changes

I Ching.
A conversation with change.

A book and an app for the modern reader — on how an ancient Chinese book of divination became a tool for reflection for Jung, Cage, and millions of people asking themselves questions with no ready-made answers.

Book

Sixty-four hexagrams,
one conversation with change.

A complete guide to the I Ching — from the book's history and the mechanics of casting, through the psychology of Jung and Pauli's synchronicity, to an in-depth interpretation of each of the 64 hexagrams, drawn directly from Richard Wilhelm's original 1924 German edition.

I Ching. A Conversation with Change

A guide to the Book of Changes for the modern reader

This book isn't another mystical self-help guide. It's a meeting of an ancient text with solid history, psychology, and practice — written to be read cover to cover, not just opened on occasion.

Each of the 64 hexagrams has four layers: the original interpretation from the Wyrocznia I Ching app (essence, the noble one's path, the lesson, the question), a classical deep dive — the core of the judgment and the image, drawn directly from Richard Wilhelm's 1924 German original — and short texts for all six changing lines.

The app and the book are independent products — you can use either on its own. But the knowledge in the book meaningfully deepens your understanding of the I Ching and lets you interpret the hexagrams you cast in the app on a deeper level: with full historical context, all six changing lines, and Wilhelm's classical commentary — none of which you'll find in the app itself.

App — free

The I Ching oracle in your pocket.

The same interpretive depth behind the book, in an app for daily reflection. Toss coins the way it's been done for thousands of years, or ask the oracle with a single tap.

  • All 64 hexagrams

    Essence, the noble one's path, the lesson, and the question for every hexagram — written from scratch, not copied from classical translations.

  • An authentic casting method

    Virtual coins that generate genuinely random lines, exactly following the classical three-coin method.

  • §

    A history of your questions

    Come back to earlier castings and watch how what you ask — and the answers you get — change over time.

A direct Android build — while we wait for Google Play approval. Requires enabling "install from unknown sources" in your phone's settings.

The app works fully on its own and is free. But if you want to interpret the hexagrams you cast on a deeper level — with full history, all changing lines, and Wilhelm's classical commentary — reach for the book. It's a separate product, but built to genuinely deepen the knowledge the app gives you.

Wyrocznia I Ching
The book's voice

Four principles that guide every interpretation.

Both the book and the Wyrocznia I Ching app draw their interpretive voice from four cardinal Confucian virtues — these, not a fortune-teller's pose, are the backbone of how the oracle's answers are formed.

Ren

Benevolence as a starting point — understanding comes before judgment.

Yi

Righteousness as radical responsibility for your own choices.

Li

Respect for form — how you act matters as much as what you do.

Zhi

Wisdom that recognizes the lasting laws governing change.

Author

Robert Kucharski

Creator of the Wyrocznia I Ching app and author of this book. For years he's paired the practice of consulting the I Ching with a question: how can this ancient book of change say something true to someone who doesn't believe in fortune-telling, but does believe in the value of pausing and asking themselves a good question.

All of the book's substantive content and its footnote format were additionally verified by AI language models — a fully disclosed process, described in a note at the end of the book.
